SEPARATE SECTIONS
Students should be able to:
- summarize and compare the life processes of respiration and photosynthesis
- label a diagram of a flower and correctly match each part with its function
- label a diagram of a cell and state the function of each part
- compare and contrast the structure of bacterial, plant and animal cells
- use a Punnett square
- locate an element on the Periodic Table, and determine its atomic number, atomic mass, and the number of protons, neutrons and electrons.
- Interpret a solubility curve
- Identify a circuit diagram or drawing as a series or parallel circuit, and state the benefits and drawbacks of each
- Using the Periodic Table, identify an element as a metal, nonmetal or metalloid
- List differences between asexual and sexual reproduction
